摘要： A data recording disk file uses a laminated suspension for supporting a negative pressure slider in a manner which prevents the read/write transducer on the slider from contacting the disk surface and which eliminates the effect of stiction. The laminated suspension is a flat, flexible sheet of material bonded on both sides to patterned metal layers. The suspension comprises an arm portion for attachment to the actuator support arm, a slider portion to which the slider is attached, and a link portion interconnecting the arm and slider portions. The first metal layer is preferably stainless steel and the second metal layer is preferably copper. The arm and link portions of the stainless steel layer are spaced apart to form a hinge of flexible material. The portion of either the copper or stainless steel near the hinge region is prestressed or bent so that the link portion of the laminated suspension is biased toward the disk surface. A second similar hinge region is located between the link and slider portions of the laminated suspension and the copper or stainless steel near that hinge region is similarly bent so that only one edge of the slider contacts the disk surface when the disk is not rotating. When the disk file is turned on and the disk is at sufficient speed, the static pressure differential between opposite sides of the suspension and the slider overcome the spring forces in the two hinge regions and pull the slider into its air-bearing operational relationship with the disk surface.
摘要翻译：描述了在数据记录盘文件中使用的层叠悬架，其以防止滑块上的读/写传感器（71）接触盘表面并且消除了静电影响的方式支撑负压滑块（66）。层压悬浮液是一种平坦的，柔性的材料（10），其在两侧结合到图案化的金属层（12,14）上。悬架包括用于附接到致动器支撑臂（66）的臂部分，滑块附接到的滑块部分和将臂和滑块部分互连的连杆部分。第一金属层优选为不锈钢，第二金属层优选为铜。不锈钢层的臂和连接部分间隔开以形成铰链（43）柔性材料。铰链区域中的铜的部分被预应力或弯曲，使得层压悬架的连接部分朝向盘表面偏置。第二类似的铰链区域（47）位于层压悬架的连杆和滑块部分之间，并且铰链区域中的铜类似地弯曲，使得当盘未旋转时，滑块的仅一个边缘接触盘表面。当磁盘文件打开并且磁盘速度足够时，悬架和滑块的相对侧之间的静压差克服了两个铰链区域中的弹簧力，并将滑块拉到其与空气轴承的操作关系磁盘表面。

摘要： A suspension system for supporting a magnetic read/write slider comprising a load beam, a slider support member and a flexure comprised of a first flexure arm and a second flexure arm. A plurality of electrical conductors extend along the edge of the load beam on the side of the load beam farthest away from the disk hub. The electrical conductors are positioned adjacent to, but outside of, the second flexure arm, so as not to contribute to the stiffness of the second flexure arm. The electrical conductors are comprised of a laminated material which includes a conductor layer, such as a high strength copper alloy, a dielectric layer and a support layer. In another embodiment, the flexure includes a first flexible finger recion and a second flexible finger region. A first plurality of slots extend completely through the first flexible finger region, and a second plurality of slots extend completely through the second flexible finger region for providing regions into which the electrical conductors can move when the flexure undergoes deflections.

摘要： A flexure for use in a head gimbal assembly comprising a single narrow torsion beam that connects a suspension load beam to a slider support member. The flexure is centered underneath a read/write slider and may be comprised of a laminated material having a conductor layer, a dielectric layer and a support layer. A plurality of electrical leads may be formed in the conductor layer for attachment the slider. The slider is mechanically attached to the slider support member by a first set of solder balls the height of which create a space for accommodating deflections of the flexure and allowing the electrical leads to pass underneath the slider. Electrical connections to the slider are made using a plurality of right angle fillet joints between the slider and a second set of solder balls on the slider support member. The shape of the torsion beam may be varied to yield different levels of stiffness to pitch, roll and yaw movement of the flexure.

摘要： A disk drive has an improved electrical interconnect assembly for coupling one or more conductive paths leading from a read/write head with the conductive terminals of a flexible cable. The improved interconnect assembly includes an interconnect tab with a plurality of interconnect pads attached thereto. The interconnect tab is connected to a suspension assembly containing a planar suspension member which is located and secured on the actuator arm such that the interconnect tab extends beyond the peripheral edge of the actuator arm. The interconnect tab is inclined toward the side of the actuator arm opposite the side on which the suspension assembly is mounted. The end of the inclined interconnect tab extends to a distance from the planar suspension member approximately equal to half the thickness of the actuator arm. The flexible conductive cable has conductive paths connected to an array of terminals which is oriented at an incline wherein each terminal is aligned with a corresponding interconnect pad. Each flexible cable terminal and corresponding interconnect pad defines an L-shaped joint that is electrically coupled by an electrically conductive fillet, thereby electrically interconnecting the read/write head to the flexible conductive cable. More than one suspension assembly utilizing this improved electrical interconnect assembly can be secured to a single actuator arm and multiple actuator arms can be used in a single disk drive. The interconnect assembly allows the disks to be spaced closer together by better utilization of the vertical space occupied by the actuator arms and disks.

摘要： A reference plane is added to the freestanding conductors of a wireless suspension to maintain a continuous reference plane therein. Post processing steps to the flexure are used after the underlying steel has been etched and prior to any forming or welding steps. Two screens are used to add an insulator layer and a conductor layer, such as copper, in the areas of the freestanding conductors. The insulator screen is sized to allow an insulator to overlap the original polyimide. The copper screen for the reference has a slightly longer screen pattern than the insulator screen. The conductor screen is sized such that the reference will overlap the insulator and make contact with the underlying steel at both ends of the freestanding conductors.
